Application

Application Challenges

Large Diameter & Deformation

Very large bearing and flange diameters increase sensitivity to structural deformation.

Complex Combined Loads

Large equipment may carry axial, radial, moment and dynamic loads simultaneously.

Custom Interfaces

Projects often require unique gear, hole pattern, ring height and central opening.

Low-speed Continuous Duty

Large rotary systems often operate slowly but continuously under high torque.

Transport & Installation

Large bearings require planned lifting, packaging, assembly and on-site handling.
